Privacy and Identity Management on Mobile Devices: Emerging Technologies and Future Directions for Innovation

Abstract

Secure Elements have been around as identity providing modules in Mobile Services since the creation of the Mobile Phone Industry. With an increasingly dynamic environment of Mobile Services and multiple Mobile Devices, however, and with an ever changing ecosystem, characterized by new value chain entrants, new (partial) identities need to be provided for the end users. Here, emerging Secure Elements such as Stickers and Secure SD cards can be leveraged in addition to the omnipresent SIM card / UICC. For future services though, even more flexible, secure and privacy enhanced Secure Elements, such as Trusted Execution Environments can be expected. They are needed to cope with an ever more dynamic Mobile Services environment that depends upon reliable, partial identities of the end users and increasingly calls for privacy and security measures. This chapter elaborates upon the emerging and future Secure Element technologies for Mobile Devices. These technologies shall allow an increasingly dynamic creation of services between front-end Mobile Devices and back-end Servers. The Chapter sets the current developments of the ecosystem for Mobile Services into perspective with the needed technologies, reflects on the contributions of the PrimeLife project and draws attention towards the still needed future directions of innovation.
